IPC: H04N5/372
Filed: 1992-08-19
Abstract: PURPOSE:To reduce the size of a solid state image pickup device by forming an air layer between an image area and a glass substrate to improve the airtightness between the glass substrate and a solid state image pickup element chip and also to omit an exclusive frame body. CONSTITUTION:A solid state image pickup element chip 2 is gang-bonded to a glass substrate 3 with a gap formed between them with many columnar bumps 7.

Title: Evaluation of semiconductor substrate
Inventor: KOIKE YASUO
IPC: H01L21/304
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To enable observation on the entire surface of substrate to a predetermined depth in a wide range and with high sensitivity, and evaluation from the observation, by increasing the size of pits formed by etching and exposing the surface of the substrate, and measuring a pit density by a laser foreign matter detecting device. SOLUTION: Oxygen precipitates l are cleaned with aqueous solution having HF concentration of 20 to 50% for about 30 minutes, thus the oxygen precipitates 1 exposed on the surface of a wafer are dissolved. The HF cleaning forms pits 2 on the wafer surface. The density of pits 2 is measured by the laser foreign matter detecting device. The current minimum detection size of the laser foreign matter detecting device is about 110 nm. If there is a pit of a size smaller than this size, all the pits cannot be measured. Accordingly, cleaning is performed 5 to 10 cycles (10 minutes/cycle) by using alkali cleaning liquid composed of NH4 OH/H2 O2 /H2 O, attaining a comparatively large amount of silicon etching. The cleaning greatly changes the width of pits 3.  Next, the laser foreign matter detecting device may detect oxygen precipitates of about several 10 nm, in defective distribution on the entire wafer surface.

Filed: 1989-08-28
Abstract: PURPOSE:To improve the radiation efficiency of X-rays by using a target comprising a substrate having the X-rays permeability and a target film made of the material which receives electron and radiates X-rays and formed on the substrate. CONSTITUTION:A target 4 for an X-rays generating tube basically consists of a substrate 1 in disc and a target film 2 formed on the substrate 1 except for the peripheral part thereof. The substrate 1 is made of the material having the fine X-rays permeability and the fine heat conductivity, for example berylium, and the target film 2 is made of the material which receives electron and radiate X-rays and formed by a method such as vacuum evaporation or the like, and the desirable thickness is the required minimum thickness to generate X-rays. The absorption of X-rays in the target film 2 is thus restricted at minimum, and since the target film 2 is held by the substrate 1 having the appropreate mechanical intensity, deflection is hard to be generated. An X-ray generating tube which radiation efficiency is improved can be thus obtained.

IPC: C30B15/26
Filed: 1992-07-28
Abstract: PURPOSE:To automatically lower a seed crystal on a molten material surface and bring the seed crystal into contact with the molten material surface in the single crystal producing device by the CZ process. CONSTITUTION:A television camera is provided to observe the solid-liq. interface, a threshold level L is set slightly lower than a video signal level M of the molten material surface by utilizing a point where the brightness of the molten material is lower than that of a seed crystal, and a pulse 8 is generated for the video signal below the threshold level L. The pulse 8 is generated when the seed crystal is lowered into the field of view of the television camera, the count is gradually increased, however the increase in the number of generated pulses is stopped because, when the tip of the single crystal penetrates into the molten material, the penetration part is still above the threshold value L. Accordingly, contact of the seed crystal with the molten material is detected by detecting the point where the increase in the number of generated pulses is stopped, and the lowering of the seed crystal is stopped at that point of time.
